Consider the equation

\sqrt{x^{2} - 2 x + 1} = x + 2

and the equation which arises from this equation by squaring both sides of the equation, i.e. the equation

{(\sqrt{x^{2} - 2 x + 1})}^{2} = (x + 2)^{2} .

Identify a true statement.

Both equations are equivalent only if

x \geq - 2

Both equations are equivalent.

Both equations are equivalent only if
